loki...
congratulations for getting custody of your kids...
i wouldn't worry too much about the court giving custody back to your ex... i mean asshole...
once you've gotten custody based on the mother's behavior, the likelihood that she would regain custody s roughly equal to the likelihood that that i could fly away like a hummingbird any time soon...
don't hold your breath...
you've already won the war (custody), a few more skirmishes and it will all be over with, is my guess...
